I have a doubt appreciate if you could answer it. If both Permission Sets and Sharing Settings is used to open-up access over-riding OWD, what is the difference between Permission set and Sharing when functionality is same i.e to extend access to data and when do you use which feature. when 10 people have the same profile and only one user needs access to extra permission, I can create permission set, why not sharing rule? In which scenarios do you use Permission set and Sharing Settings please explain with examples.
